Update on Direct Instruction: Exposing a Silly Study

Those interested in the educational technique of Direct Instruction may have heard about a study published in 1997 that claimed to show that students trained with Direct Instruction have a higher rate of being arrested. The study, published in Early Childhood Research Quarterly in 1997,  based on a sample size of 68 students, only 23 of which were in Direct Instruction. What conclusions can possibly be drawn from such a tiny sample? Siegfried Engelmann discusses the flaws of this study in his Response to "The High/Scope Preschool Curriculum Comparison Study Through Age 23."
